This invention relates to awhing type windows.

Hitherto, awning windows have been manufactured which include a series of swinging sashes pivotally and slidably mounted slidin connections include a pair of fulcrum links or each sashwhich a-repivoted inter mediate the ends of the sashes and to the 10 frame, and sliding shoes fitted to the upper ends of the sashes. and slidably engaging trackways formed in the jambs of the frame.

. In order that the sashes ma be independently operated the upper en s of the sashes u are connected together by a connecting member arranged vertically intermediate the sashes and the 'jamb. This connecting member is capable of operation to disconnect 1 the sashes so that they may be operated ingo dependently, As the fulcrum links and the connecting ember are. arranged between the sashes an d the jamb and as the connect-- ing member requires a certain amount of .clearance for operation, it was necessary that the frame be of considerable depth. In wood construction there is ample space for theseelements and such construction results in an ideal arrangement for windows of this type butwhenendeavoring to convert these windows intoall steel construction the steel frame must be ofa design substantially the same in dimensions as the wood type frame. were veryexpensive to manufacture, ex-

' It is the principal object of the present invention to provide a comparatively inexpensive awning e-window operating as above set forth whic can be incorporated into a steel frame of simple design and of minimum dimensions.

One form which the invention may assume is exemplified in the following description and illustrated by way of example in the accompanying drawings, in which Fig. 1 is a central vertical section throughmanentl a window structure embodying the preferred form of my invention and disclosing the sashes open position.

Referring more particularly to the accom-" panying drawings 10. indicates a window frame of suitable dimensions and construction. This frame is formed of bars of channeled material as illustrated in the drawings. This material is of a-standard shape and stock and is principally used in the manufacture of window frames for factories, schools and other buildin using metallic trim. -Windows having rames constructed of this material are durable, comparatively inexpensive and have a maximum area of glass.

The frame 10 is formed with two sash openings 11 within which sashes 12 and 14 are mounted for swinging movement in a vertical plane. Each sash is connected with the frame by a pair of fulcrum links 15. These fulcrum links-- are disposed exteriorly of the window as illustrated and are pivotally connected at their lower ends to lugs 16 perfixed on the exterior face of the jambs o 'the frame. 1

It will be noticed that the links of each sash are arranged upon opposite sides thereof 100 tween the links andthe frame.

and in horizontal alignment. The upper ends of the fulcrum links 15 are pivotally connected to the sides of the sash at a pointintermediate the ends of the latter. The point of connection between the links 15 and the sash is spaced further from the face of the frame 10 than the point of connection be- This' arrangement of the pivotal points of the fulcrum links causes thesashes to tightly close and remain so-when the sashes are drawn to closed position.

The upper end of each sash is pivotally and slidably connected to the j ambs of the frame so that the sashes will pivot about their upper ends in a vertical plane as illustrated in Fig. 1 of the drawings. Included in the pivotal connections between the sashes and the jambs of the frame is a pair of travelling or actuating bars 17 disposed one'adjacent each jamband nested within the channeled portion thereof intermediate the sash and the jamb. The upper sash is fitted at its top rail with a pair of outwardly projecting connectors 18 which are constantly urged outwardly by springs 19. v

The connectors 18 and springs 19 are housed within barrels 20 suitably secured to the upper rail of the sash. These connectors 18 project beyond the sides of the sash and engage sockets 21 formed in the inner surfaces of the travelling bars 17 The connection be-' tween the uppelfsash and these travelling bars forms a pivotaland sliding ,conneetion' between the upper end of the upper sash and the jam bs of the frame, enabling operation of the upperv sash as the travelling bars 17 may reciprocate in the channeled jambs.

. It is desired to point out that the springs 19 which tend to press the connectors 18 outwardly cause a certain amount of friction between 'the travelling bars 17 and the jambs 0f the frame so that the sashes will remain .inv any set position, but may be operated .the travelling bars 17. The movement of-the connectors 18 is limited, however, so that they cannot be withdrawn from the shoes 22.

Thus, when the connector-s18 are withdrawn from engagement with the sockets 21 in the travelling bars 17 a sliding and pivotal con- V nection will be established between the upper end of the lower sash and the lower ends of the travelling bars 17, so that the sashes may be operated independently of each other.

It will be noticed that the travelling bars 17 extend a considerable distance below the point of connection between them and the lower sash so that ample guide means will be provided for the lower sash when it is operated'independently of the upper one.

, In operation of the window, it is constructed ind assembled as illustrated in the.

The disposition of the pivotal points of the 1 fulcrum links 15 upon which the sashes are suspended will cause the sashes to tightly close when they are drawn to this position.

To operate the sashes independently it is only necessary to operate'the member 24 to withdraw the connectors 18 from engagement Withthe sockets 21 in the travelling.

bars 17. Either sash may then be operated independently of the other. As soon as the operating member 24 is released and the connectors 18 of the lower sashaligned or registered with the sockets 21 on the travelling bars 17, they will re-engage these sockets and connect the sashes together.

It is desired to point out here that although two sashes are shown in the present instance, it should beunderstood that a greater number of sashes may be arranged in a sin le frame if desired and still be operated y means of the mechanism here disclosed.

Particular attention is directed to the fact that the depth of the frame is no greater than the depth of the sash rails themselves, and that the operating mechanism with the exception of the fulcrum links 15 is all concealed, when the sashes are closed.

Also, the frame is constructed of standard material and the operating mechanism is so designed that it will be inexpensive to construct, enabling the window to be produced at a figure far less than awning type windows of present day construction.

While the preferred form of the invention has been here disclosed, it is to be understood that various changes may be made in its construction by those skilled inthe art without de arting from the spirit of the invention as defined in the appended claims.
